Although environmental management in Turkey is evolving, its performance needs to be assessed in terms of the extent to which polluters and dischargers are complying with their legal obligations. In spite of this necessity, however, not a single study evaluating the effectiveness of command-and-control strategy of environmental management has been conducted. It is for this reason that it was decided to conduct an analysis of the impact of environmental legislation on a major industrial area in Turkey. Accordingly, Turkish environmental legislation was analyzed, and all relevant obligations and responsibilities of industry are identified. Based upon this appraisal, a questionnaire was prepared and used to conduct interviews in Tuzla, Istanbul. From the results, it can be concluded that environmental compliance performance of industry is low. The total of 92 parameters has been questioned. Fifty-three parameters have been found as satisfactory compliance, whereas 26 parameters have been classified as partial compliance and 13 as unsatisfactory compliance. The most important reason for inadequate performance is the lack of an effective national and local environmental compliance management system. The other leading reasons are found to be low-level environmental consciousness of the people, absence of environmental management system at the sites, inadequacies in environmental subsidies, and insufficiencies in public environmental infrastructure. Four recommendations are made to increase the effectiveness of compliance management: establishing an effective environmental compliance management system, accelerating public investment for environmental infrastructure, developing financial subsidies and incentive schemes for environmental investments, and encouraging voluntary initiatives.
